How Texas Tax Sales Differ
Source: Texas Signals — aggregate county data.
Most states sell tax lien certificates, where the investor purchases the right to collect delinquent taxes plus interest. Texas does not use the certificate system. Instead, Texas sells the actual property at auction — a tax deed sale. This is a critical distinction:
•Tax lien states — You earn interest on the lien; if the owner pays, you get your investment back plus penalty
•Texas (tax deed state) — You buy the property itself, subject to a redemption period
The redemption period in Texas:
•Non-homestead properties: 6 months (owner pays you 25% premium to redeem)
•Homestead properties: 2 years (owner pays you 25% in year 1, 50% in year 2)
Bexar County Tax Delinquency Data
The Bexar County tax landscape presents unique challenges. The county's tax assessment system uses the JSP-based online portal, which makes bulk data collection difficult. Texas Signals currently tracks a limited dataset of Bexar County tax delinquent properties, with ongoing efforts to expand coverage through the Playwright-based scraper system.
Key observations from available data:
Assessment Increases
Bexar County Appraisal District reappraised properties in 2025, resulting in average assessment increases of 8-12% across the metro. These increases compound the tax burden on already-stressed owners, particularly in neighborhoods where incomes have not kept pace.
Military Community Impact
San Antonio's large military population creates a specific tax delinquency pattern. Service members who PCS (Permanent Change of Station) sometimes retain properties as rentals. When the rental income does not cover the tax-inclusive mortgage payment, delinquency follows, often 12-18 months after the owner has relocated.
East Side Concentration
The East Side of San Antonio (78202, 78203, 78220) has the highest density of tax delinquent properties. These areas also have some of the lowest property values in the metro, creating opportunities for investors with modest capital.
The Tax Sale Process in Bexar County
1.Delinquency accumulates — Taxes become delinquent on February 1 of each year
2.Penalty and interest accrue — 7% penalty in February, 2% per month through June, then additional fees
3.County files lawsuit — After approximately 2 years of delinquency
4.Court judgment — Court orders the property sold
5.Auction — Bexar County holds monthly tax sales (first Tuesday)
6.Minimum bid — Total amount owed (taxes, penalties, interest, legal fees)
Finding Opportunities
The best tax sale opportunities share these characteristics:
•Properties with significant equity — The tax debt is a fraction of the property value
•Clear title — No mortgage or other senior liens (if there is a mortgage, the lender usually pays the taxes to protect their interest)
•Habitable condition — The property can be rented or sold without major renovation
•No environmental issues — Particularly important for commercial or industrial-adjacent properties
Risk Factors
Redemption
The redemption right means your investment is not final for 6 months to 2 years. You cannot make significant improvements during this period without risking loss if the owner redeems.
Condition
As with foreclosure auctions, you cannot inspect the interior before purchase. Tax sale properties often have deferred maintenance issues that exceed expectations.
Title Complexity
Tax deeds in Texas are considered inferior title. Most title companies will not insure a tax deed without a quiet title action (lawsuit to establish clean title). Budget $3,000-$7,000 for this process.
